` To all whom may concern.'

Be it known that I, AUGUSTUS C. FELToN, J r., a citizen ofthe UnitedStates, and a res-y ident of Macon, in the county of Bibb and State of Georgia, have invented certain new and useful Improvements in Crematories, of

' which the following is a specification. r

' My invention relates to improvements in crematories, and it consists in the combinations, constructions and arrangementsherein described and claimed.

An object of theinvention is to provide a creniatory which affords facilities for utilizing in the incineration of waste matter and refuse, practically all ythe lieatfgenera-ted within the crematory.

vA still further obj ect of the invention is to provide a crematory which is constructed in such inaniier as to permit pre-heating ofthe intake air forsupporting combustionthere# within by the heat of the exhaust gases and products of combustion, which heat wouldl ordinarily escape from the crematory with-l out accomplishing any useful purpose.

A still further object of the invention is to provide a crematory having means for conducting the heated products ofthe conibustion `a relatively great distance in contiguous relation to the walls of a combustion chamber of the crematory before permitting such products of combustion to pass from the creniatory,whereby a high tem perature is maintained within the combustion chamber and the accumulated heat within the crematory .is utilized'to a relatively great extent. p.

A still further object of the 'invention is to provide a crematory `of simplified construction which embodies a novel and simple arrangement whereby fuel may be readily fed to the combustion chamber and the heat con# ducting4 passages of the creinatory may be conveniently cleaned.

Other objects and advantages willbe ap; parent from the following description, and

the novel features of the invention willbe in` the appended particularly outlined claims.

My invention is illustrated in the accompanying. drawings, forming a part of this application, in which:-

Fig. 1 is a horizontal sectional view taken through the lower portion of a furnace-or' creinatory embodying the invention and through the walls of a Structure aS.SQciated` withv the Clematory,

Fig. 2 is a fragmentary longitudinal vert-iend portions of the creinatory and associated structure, y Figs. '5 and l6 respectively are sections taken substantially on the lines 5-.5 and 6-6 of Fig. 2, Fig. 7 is a fragmentary vi section and partly in side elevation, showing ak portion of the crematory, a ventilator provided therein and a hot water tank positioned at one ,endv of the crematory, and

Fig. 8 is an end viewfof the structure shown in F ig.` 7 portions thereof being broken away to` show ythat the heating coils of the water tank are disposed within a flue ofthe crematory.

Referring now 'to the drawings and'inore particularly to Figs.l l, 3 and 4 thereof,it will be observed thatthe invention contemplates tlie provision of a combustion chamber A` having side walls A1 and A2. and end walls A3, A4 surmounted by aroof A5 which is arched between the side walls, fas is usual in furnaces of the reverberatory type of construction. l f

The bottom or floor of the combustion vchamber A consists of a grate section A6 upew, partly in f with their bases or bottom walls in the plane f of the'upper rside of the grate section A6 so that fuel may be conveniently fed to the grate section. The openings Alo'preferably f correspond in number with the openings Av and are relatively arranged so that a fuel feed opening yis provided above each of the clean-out openings A9. Doors A11arepro vided to controlthe clean-out openings A'J and the openings A10 'are normally closed by doorsAlz. y v

lt is to be observed at thispoint that the uppersides of the juxtaposed lower sections i Aand A7 lie in substantially the'saine hori- Zontal plane and that'each occupies'approximately half of the area of the bottom of the' f combustion Chamber.

within the combustion chamber `will be` in-` creased to a relatively high degree in a minimuin of time.

The crematory structure may be braced and reenforced by vertical brace members or buck bars W arranged at opposite sides thereot` and being connected .by the rods W extending through the side walls of the crematory structure.

From the foregoing description of the various parts ot the device, theoperation thereof may be readily understood. Wet

" garbage, night soil and other retuse'w'hi'ch are to be incinerated, may be dumped through the chuteor chutes X upon the pany A". A suitable fuel, introduced within the combustiony chamber through the -fuel vfeed openings A to rest upon the grate section A is ignited in any suitable known mannerV and the combustion thereof may be supported at the beginning of the 'operation or' throughout the operation if desired,-by a more readily combustible fuel, such as oil,

passages Q, R, Rf, R2 and N1, N, N2, N3 to the space beneath the grate section As at opposite ends of the latter. lt is to be observed at this point that the intake air is heated because of contact with the arched roof A5 in passing from the ventilators V to the passages Q and N1. kThe intake air is further heated during its passage along the passages. Q., R, R and N1, N, N2, being heated to a relatively high temperature because of contact with the `walls of the pre-heating passages R and N, which are heated in a manner to be hereinafter described.

The heated intake air passes upwardly i through the grate section and supports combustion in the usual manner. rThe heated products of combustion pass from the grate passages P which are locatedat the end of the pan remote from the stack S. As stated, the bottom wall of the passage N is the upper wall off the passages P and in consequence, the walls of the pre-heating passage N are kept continuously at a relatively high temperature by heatk from the gases and products of combustion passing through the exhaust passage P. The passages P communicate with the lues F at the ends of the latter remote from the stack S and the heated products' of combustion must therefore travel the entire length of the combustion chamber in underlying proximity to the pan A7 beforey such products of combustion are permitted to enter the stack S.

The walls of the pre-heating passage R` are maintained in heated condition because of their proximity to the stack S and to the lues F which underlie the bottom wall of the passage R, asbest seenin Fig. 2.

' It will thus be apparent that practically all theheat created by the combustion of a given amount of fuel within the combustion chamber isutilizedy in the drying kandincineration of garbage` and other refuse dumped uponthe pan A7. The heated gases and other products of*combustion are conducted by a circuitous lroute from the combustionchamber to the stack and the heat from such products of combustion is utilized Ato, rdry the wet garbage and other refuse u'p'onthe pan A7 to cause direct Contact therewith, kto lreepthe walls of the combustion chamber and thepan AT' heated and to therefore effect the pre-heatingy of intake air before the latter reaches the grate section and the 'thorough drying of the matter which is to be incinerated. A relatively high temperature is thus maintained continuouslyv within thel combustion chamber and a. crematory 'having relatively high eiiiciency is thus provided. l

`The arrangement of the ,grate section 6 and the feed and'clean-ou-t openings associated therewith is such as to permit of fuell being supplied conveniently to the grate section and the'c'onvenient and easy vcleaning of the ash pit. l.`\/loreover, the provision of the clean-out openingsr at the ends of the flues F permits of the cleaning of these lues and preventsvthe accumulationtherein of carbon deposits or liker matter which might detrimentally aiect the operation of the device. f f

Obviously my invention is susceptible of ,l

embodiment in `forms other f than that in which illustrated in the accompanying drawings, and I therefore consider as my own all modiiications and adaptations thereof which fairly fall within the scope of the ap pended claims.

I claim 1. A crematory structure comprising vertical side and end walls, a charging floor section supported upon the vertical side and end walls, a floor consisting of juxtaposed grate and garbage supporting sections, an arched roof. overlying the floor and being spaced from the charging floor, said side wall having an inlet therein for admitting air to the space between the roof and the charging loor, walls cooperating with the said end walls and the arched roet for conducting the admitted air by tortuous paths from the inlet to a space below the grate section, a stack adjacent to one of said end walls, said garbage supporting section having a iue` extending longitudinally thereof in adjacent underlyingy relation to the supporting surface thereof and-being spaced from the end wall ot the crematory remote from the stack to provide a port establish- 'ing communicationbetween the one end of said iflue and the space Within the ereinatory structure belovi7 the arched rooi", said AHue be f in open communication at its opposite end with the stack, and a charging chute depending from the Charging floor through the arched roof.
